<P class="title"><A NAME="HELPCmdU"></A>Command <B>U</B> - update
files within an archive<hr></P>

<P>This command, as well as <A HREF="HELPCmdF.htm">command f</A>,
updates files in the archive only if they are older than files being
added, but unlike "f", it will add new files as well. </P>

<P>This is the command line equivalent of the command <A HREF="HELPCommandsAdd.htm">
Add to archive</A> with "Add and update files" update mode selected
in the <A HREF="HELPGetArcName.htm">Archive name and parameters dialog</A>.</P>


<P>Because archive volume modification is disabled, this command is
not applicable to volumes.</P>

<P><B>See also: <A HREF="HELPCmdA.htm">command A - add files to archive</A>
